en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/lldb/test/API/commands/thread/backtrace/Makefile#635f03fe Add a repeat command option for "thread backtrace --count N".This way if you have a long stack, you can issue "thread backtrace --count 10"and then subsequent <Return>-s will page you through the stack.This took a little more effort than just adding the repeat command, sincethe GetRepeatCommand API was returning a "const char *". That meant the commandhad to keep the repeat string alive, which is inconvenient. The originalAPI returned either a nullptr, or a const char *, so I changed the private API toreturn an llvm::Optional<std::string>. Most of the patch is propagating that change.Also, there was a little thinko in fetching the repeat command. We don'tfetch repeat commands for commands that aren't being added to history, whichis in general reasonable. And we don't add repeat commands to the history -also reasonable. But we do want the repeat command to be able to generatethe NEXT repeat command. So I adjusted the logic in HandleCommand to workthat way.Differential Revision: https://reviews.llvm.org/D119046 List of files: /llvm-project-15.0.7/lldb/test/API/commands/thread/backtrace/Makefile Fri, 04 Feb 2022 23:16:31 +0000 Jim Ingham <jingham@apple.com>
